The issue of protecting their territory and personal property is always of interest to every owner. Often the owners of a suburban area have a watchdog, but if a person is rarely at home, the problem of feeding the animal arises. In this case, an electronic device comes to the rescue. Now it is very popular to give a GSM alarm clock or its other variant – Smart Sentry. Although, besides it, there are other similar types of security systems, but they all work on the same principle.
How GSM alarm system works
The modern market offers a lot of security devices. In addition to the Smart Sentry, the Dacha 01 GSM system has proven itself well. It can also be found under the name TAVR. However, no matter how the brand is named, the main element of any GSM system is the sensor. When an intruder tries to enter someone else’s territory, he enters the range of the electronic device. A triggered sensor instantly sends a signal to the phone of the owner of the cottage.
Modern security systems with a GSM module can be equipped with several sensors that play a different role, for example, a microphone or a video camera. This allows the owner of the cottage to hear and see the full picture of what is happening on his territory. Thanks to the microphone, the owner at any time has the opportunity to use listening by calling the phone to the cottage.
The main types of GSM security systems
Regardless of the brand of the security system, all GSM alarms differ in the installation method:
- The wired model provides for connecting sensors to the main unit using wires. This is often very inconvenient, plus a low level of security. If the wire is damaged, the sensor will not be able to send a signal. That is, the object remains unprotected.
- The wireless model uses a radio channel. The signal from the sensor at a certain frequency is fed to the main unit, which, in turn, sends it to the programmed phone number.
Both types of alarms can be connected to the mains or autonomously. The second option is most acceptable for giving. Even after a power outage, the facility will remain under protection. The autonomous system is battery powered. You just need to recharge it periodically.
Wired and wireless system, equipped with a GSM module, is able to work with many sensors. For example, the alarm is able to notify the owner of the appearance of smoke, flooding of the premises with water, gas leaks, etc. The temperature sensor is very convenient to use, which allows you to control the operation of the heating boiler and maintain the desired temperature in the room. An electronic device can even be installed on the door, and the owner will know when it was opened.
What are the parameters for choosing a GSM security system
Before choosing a GSM security system, you need to decide in what conditions it will work. Dachas are not always heated in winter, and electronics must withstand temperature changes. To do this, it is optimal to purchase a model that can work in the heat and in the cold. The next important issue is non-volatile operation. The battery capacity should be enough until the next recharging upon the arrival of the owner, if the electricity supply to the house is not restored. And, most importantly, you need to decide which sensors are needed.
Budget alarm for giving has the following functions:
- the owner can remotely learn about the operation of the system;
- arm and disarm an object over the phone;
- programming more than one number to which the GSM module will send an alert;
- the owner has the ability to independently record any text of the notification, and correct it if necessary;
- listening to the protected object.
More expensive security systems are endowed with additional features;
- change the language of the settings menu;
- voltage absence signaling device;
- sending a message about the loss of the signal;
- using different passwords;
- communication through a microphone between people located in different rooms of the building.
Very advanced expensive systems are equipped with sensors that react to the breaking of window glass, the appearance of gas or water leaks in the house, smoke, etc.
Complete set of GSM alarm
Wireless security systems from different manufacturers differ in the configuration of sensors and battery capacity for autonomous operation. Standard stand-alone GSM alarm consists of the following elements:
- main unit – GSM module;
- power supply from the mains;
- battery;
- two key fobs;
- door opening and movement sensor;
- USB cable to connect to a PC to make settings.
Depending on the model, alarms can be equipped with additional sensors and buttons for alarming.
GSM module
The block is the heart of the system. The module receives signals from all installed sensors. After processing the information, the electronic device sends a message to the specified phone numbers. To activate the system, a SIM card is installed in the module. An important condition is the absence of a PIN code request. In addition, the card should contain only those numbers where the signal will be sent. All others must be removed.
Sensor kit
From the very beginning, you need to decide what sensors are needed for reliable protection of the dacha. Undoubtedly, the first place is given to electronic devices that respond to movement. There are many such sensors. They are installed around the perimeter of the site, near windows, front doors and inside the house. Motion sensors work on the principle of infrared radiation, so they are easy to disable if covered with something. For inaccessibility to the device, installation is carried out at a height of about 2,5 m.
It does not hurt to put a reed switch on the front door. These door open sensors have several varieties. Reed switches are produced with response sensitivity on large steel gates and standard ones for PVC or wooden doors.
If the cottage is left unattended in winter, it will not be superfluous to put a glass breaking sensor on each window. All other electronic devices that react to gas, smoke, water are optional. Such sensors are more needed for their own safety.
Sound sirens
A sound siren is needed to scare off intruders from the country house. When a danger signal is received from the sensors to the GSM module, it in turn sends an impulse to an electronic device that emits a loud sound of about 110 dB. The sound siren will notify neighbors in the country about the possibility of breaking into housing. They will immediately call the police or independently examine your site.
Wireless keyfobs
Usually, any GSM alarm is equipped with two key fobs. They are needed to turn the system on and off. The key fob may have an alarm button, when pressed, the siren is triggered. The electronic device works at a small distance from the house. If, approaching your yard, suspicious people are seen on the territory, the alarm button turns on the siren to scare them away.
Video surveillance sensor
This electronic device is equipped with a video camera. She shoots everything that falls into her field of action. When danger occurs, shooting starts automatically. The GSM module starts sending captured frames to the specified phone numbers. The block can even be programmed so that the captured information will be sent to the e-mail specified by the owner of the cottage.

Conclusion
The convenience of wireless alarms is due to the unlimited number of sensors. In addition to security functions, the electronic device is able to turn on the watering of the site or home heating in the absence of the owners of the cottage.
